Ink Set and Inkjet Recording Method Using the Same and Recorded Article

Abstract

An ink set comprising at least a magenta ink composition and a light magenta ink composition having a pigment concentration lower than the pigment concentration of the magenta ink composition, wherein the pigment used in said magenta ink composition is C.I. pigment red 122 and the pigment used in said light magenta ink composition is C.I. pigment violet 19.

1 . An ink set comprising at least a magenta ink composition and a light magenta ink composition having a pigment concentration lower than the pigment concentration of the magenta ink composition, wherein the pigment used in said magenta ink composition is C.I. pigment red 122 and the pigment used in said light magenta ink composition is C.I. pigment violet 19. 
   
   
       2 . The ink set according to  claim 1 , wherein the ratio of the concentration of said C.I. pigment red 122 used in said magenta ink composition to the concentration of said C.I. pigment violet 19 used in said light magenta ink composition is between 4:3 and 14:1. 
   
   
       3 . The ink set according to  claim 1 , wherein said magenta ink composition and said light magenta ink composition comprise a dispersant for dispersing the pigment. 
   
   
       4 . The ink set according to  claim 3 , wherein said dispersant is a resin or surfactant. 
   
   
       5 . The ink set according to  claim 1 , wherein said magenta ink composition and said light magenta ink composition comprise a penetrating agent for increasing penetration of the pigment into a recording medium. 
   
   
       6 . The ink set according to  claim 5 , wherein said penetrating agent is a 1,2-alkanediol and/or a silicon surfactant. 
   
   
       7 . The ink set according to  claim 1 , wherein said magenta ink composition and said light magenta ink composition comprise a wetting agent. 
   
   
       8 . The ink set according to  claim 7 , wherein said wetting agent is a polyvalent alcohol. 
   
   
       9 . The ink set according to  claim 1 , further comprising a yellow ink composition, a cyan ink composition and a light cyan ink composition. 
   
   
       10 . An inkjet recording method in which printing is accomplished by discharging droplets of an ink composition and causing the droplets to adhere to a recording medium, wherein the ink set according to  claim 1  is used. 
   
   
       11 . A recorded material which is recorded using the ink set comprising at least a magenta ink composition and a light magenta ink composition having a pigment concentration lower than the pigment concentration of the magenta ink composition, wherein the pigment used in said magenta ink composition is C.I. pigment red 122 and the pigment used in said light magenta ink composition is C.I. pigment violet 19 or by the inkjet recording method according to  claim 10 .
